Engine valve cover (car maintenance: engine problems found,TNT Sports which may be caused by the valve cover!) With the continuous improvement of automobile manufacturing technology, automobile maintenance has become more and more professional. In daily driving, car engine failure is one of the most reluctant problems for drivers to encounter. The engine valve cover is an important part. If an engine problem is found, it may be caused by the valve cover! This article will introduce the function, fault cause and maintenance methods of the valve cover to help you better understand the valve cover and effectively prevent and solve related engine problems. I. The function of the valve cover. As the name implies, the valve cover refers to the parts installed on the valve in the car engine. The valve cover is generally made of aluminum alloy or steel, which has many functions such as waterproof sealing, controlling valve opening and closing and guiding gas. It is an indispensable part of the engine valve.As a key part to control the opening and closing of the valve, the valve cover is one of the main structures of the engine. Its main functions are: 1. Protect the valve: The valve cover can protect the valve, prevent external dust from entering the valve, and avoid the valve breakage or rust caused by dust entering the cylinder. Two. Sealing performance: The valve cover can play a waterproof and sealing role to prevent water vapor, heavy rain or river water from entering the engine interior, resulting in oil muddying or water rust in the engine cylinder. 3. Guide gas: The valve cover can also guide the air flowing into the cylinder, so that it forms a fine gas flow in the combustion chamber, thus improving the fuel economy of the car. II. The reason for the failure of the valve cover Although the valve cover is one of the most critical parts of the engine, it is still possible to fail, and even cause the engine to fail to work properly. Common valve cover faults mainly include the following: 1.Deformation of the valve cover: When the car runs for a period of time, the valve cover may be deformed. There are many reasons for deformation, such as oil corrosion, high temperature, cylinder wall wear, etc. Two. Wear of the valve cover: Due to long-term friction wear, the valve cover may be damaged and cracks may appear. When the wear is severe, it may even cause the valve cover to fail. 3. Short circuit of the valve cover: Due to the short circuit of electrical components, such as the short circuit of the electromagnet circuit that drives the valve, it will also cause the failure of the valve cover. III. The maintenance method of the valve cover. In the face of various problems arising from the valve cover, it is very necessary to maintain the car, detect and repair faults in time. The following are some repair methods for common faults: 1. Replace the valve cover: If the valve cover is seriously worn, deformed or cracked, it needs to be replaced. When replacing, you can choose to use the original parts or the valve cover of the same quality.Two. Repair the valve cover: If the valve cover is not seriously damaged, such as wear or rust, it can be repaired. During repair, the valve cover needs to be disassembled, cleaned, sanded, coated and other steps to achieve the purpose of repair. 3. Maintenance of valve cover: How to ensure the long-term performance of valve cover? First, you should pay attention to the maintenance of the car, avoid overloading the engine, pay attention to the oil temperature, oil volume, oil quality, etc., and prevent the oil from aging and corroding the detailed parts. The second is to check the condition of the valve cover regularly, and check whether the valve cover is worn, deformed or cracked. In a word, the valve cover is a very important part of the car engine. In order to ensure the normal operation of the car engine, it is necessary to check the valve cover frequently. If there is a problem with the valve cover, it must be repaired or replaced in time.Only in this way can we ensure the long-term stable operation of the car engine and ensure the driving safety of the driver.
